Replacement flat battery pack for a dead mp4 player.

Works when connected to USB voltage, the battery will just not take a charge. I have it apart and replacement looks fairly straightforward, but having trouble finding ONE at a reasonable cost via Google search. Specs li-ion 3.7v 400mAh 043040, seems to be readily available in lots of 1000. Since I'm just doing this to resurrect an old favorite MP4, I don't want to spend more than 5 USD, as I can live w/o it.
